“…In this case, current control in VSD is superior as xy-currents can be exploited to correct for system asymmetries [30]. Furthermore, from drives perspective, integration of existing three-phase controls, such as flux-weakening, is seamless in VSD since the MPD is treated as a single system in the synchronous dqframe [33], [34]. For such attributes, in addition to generality, VSD modeling is favored over multiple d-q.…”

Multiphase inverters (MPIs) continue to increase in popularity owing to their compelling features that include enhanced fault-tolerance capability, improved per-phase power handling, and reduced dc-bus capacitor sizing. This article presents a comprehensive review on MPIs and their application in transportation electrification. More specifically, voltage source inverter (VSI) and nine-switch inverter (NSI) are the two MPI topologies reviewed herein, due to their popularity and potential for employment as traction inverters. The state-of-the-art review covers modeling and control techniques, dc-capacitor sizing, modulation strategies, inverter losses, and cost. Promising future trends of MPIs in terms of topologies, switching devices and integrated design are also investigated.INDEX TERMS Automotive, dc-ac converters, electric vehicles, inverters, power electronics, pulse width modulated power converters, transportation electrification, vector control.

“…After VSD transformation, the property of the α-β plane variable is similar to that of the three-phase motor, while the z 1 -z 2 plane is a unique property of the six-phase PMSM [22]. Simultaneously, the change of the z 1 -z 2 component during inverter fault is explored, which can be used for inverter fault diagnosis.…”

Compared with the three-phase motor, the six-phase motor has lower torque ripple and higher fault tolerance performance, which makes it widely used in aviation, ships, industrial manufacturing, and other application fields. However, the probability of failure of the polyphase motor system increases with the increase in the number of phases. In order to deal with the open phase fault and power switch fault of the six-phase inverter, a fault diagnosis method for the six-phase inverter based on vector space decoupling (VSD) is proposed. The open phase fault index is first determined according to the VSD decoupling inverse transform and the current constraints. The fault index is then optimized from the perspective of preventing misdiagnosis and improving reliability, and the open phase fault can be diagnosed in one fundamental cycle. In addition, the current trajectory of harmonic plane after switch fault is analyzed, and the back propagation (BP) neural network is used to identify the harmonic plane current trajectory of different types of switch fault. Finally, the correctness and feasibility of the proposed fault diagnosis method are verified by simulations and experiments. The obtained results demonstrate that the proposed method can quickly and accurately locate the open phase fault and switch fault without additional hardware. The proposed method is simple, efficient, and robust.

“…With the increasing demand for a high reliability and high-power density in high-end equipment, such as special vehicles, military ships, and electric aircrafts, DC power supply systems based on multiphase generators have gained significant attention in various fields. Multiphase generators have advantages over traditional three-phase generators, such as a low-voltage high-power, low-torque ripples, and strong fault-tolerance ability [1][2][3][4][5] . Among existing multiphase generators, the dual three-phase permanent magnet synchronous generator (DTP-PMSG) has attracted the most attention owing to its characteristics of both three-phase and multiphase generators [6] .…”

A modified four-dimensional linear active disturbance rejection control (LADRC) strategy is proposed for a dual three-phase permanent magnet synchronous generator (DTP-PMSG) system to reduce cross-coupling between the d and q axis currents in the d-q subspace and harmonic currents in the x-y subspace. In the d-q subspace, the proposed strategy uses a model-based LADRC to enhance the decoupling effect between the d and q axes and the disturbance rejection ability against parameter variation.In the x-y subspace, the 5th and 7th harmonic current suppression abilities are improved by using quasi-resonant units parallel to the extended state observer of the traditional LADRC. The proposed modified LADRC strategy improved both the steady-state performance and dynamic response of the DTP-PMSG system. The experimental results demonstrate that the proposed strategy is both feasible and effective.
